TO ALL WHOM IT MAY CONCERN:

Be it known that I, Hman Rosnnooigof Chicago, in the county of Cook, and State of Illinois, have invented new and `useful improvements in Steam-Generators; and I do hereby declare' that the following is a full, clear, and exact description oi' the construction and operation of the same, reference being had to the accompanying drawings, making part of this specification. I

Figure 1 of VSheet No. 1 represents a vertical section of one form of=my improved steam-generator.

Figure 2 is a vertical end view, taken through line W Z of tig. 1; and

Figure 3 is a top view, taken through line U V of iig. 1. i Y The nature and object of inyinvention are to construct a steam-generator to generate steam or superlreated steam in suilicient quantities -to drive an engine of any power desired, by introducing the water within the gen# erator in small quantities at each stroke oi' the piston, and thus instantaneously converting it into steam or super-heated steam. v l p The illustration on Sheet No. l, g. 1,.represeuts a generator made in longitudinal form with vertical dues. Theseues are set in rows, and slightly conical in form, and I employ anynumber required The number employed-depends upon the'capacity of the generator desired. Y l

, A and B, iig. 1, Sheet No. -1, are diaphragms, one of which is located near the top of the generator, and the other near the bottom of the same. The iiues C C C extend from one diaphragm to theother, and each tlu'e opens at both endsinto the spaces above and below the diaphrag'ms. D is a reservoir for water, located in the chimney E. F is a water pipe leading from the reservoir D, down through the upper` diaphragm A, and amid and around the series of fines C C C. The pipe F is punctured with small apertures H I-I H, of such size and ot such number, and in'sueh places as will answer the object desired; it being mainly intended that the apertures shall be so placed as to discharge the water on or near a flue. The fire-box is located at I. K is a stopcock, located in the pipe F, to'cut oii the supply oi' water to this pipe. l

The operation of my invention is as follows: The re is made in the fire-box I, and the heat and ilamc pass up through the iues C C C, as shown by the arrows. On leaving the tubes the dame and smoke pass in the direction indicated by the arrows at thc upper end of the tlues, and up through the chimney E, around the reservoir D, thus heating the Water. The water is forced from the reservoir D after it is heated, through the pipe F, and out Ithrough the various small apertures H 1I I-I. The space between the two diaphragms A and B, and exterior to the dues C C C, is kept to a heat of from 300 Fahrenheit to the degreeI required, ,The Water being discharged from the tube F through the small apertures H I-I H into this space, is instantly converted into steam or superheated steam, whence it is led 4through pipes into the cylinder, to discharge its duties.

I do not confine myself to any particular and special arrangement of the pipe F, but reserve the right to locate it as circumstances may require with respect to the tlues C C C. It will be observed that in this method of constructing a steam-generator I am enabled to secure a greater or less amount of heating surface,V in proportion as I employ a greater or less number of tlues C C C. In proportion as are the degrees of `heat in the space into which the water is discharged, am I able to convert instantaneously the water into superheated steam. It is a well-known fact that the power of supcrheated steam is far greater than ordinary steam, and by this method of constructing asteam-generator' I am enabled to secure the ull advantages of superbes/ted steam, as well as any space desired formaking the same. y

Sheet No. 2 represents another form, wherein the fines C C C are straight. n

Sheet No. 3 represents another v'i`orm,lwherein the dues C C C are arranged in circular form, with the pipe F winding around theselues, as circumstances should' require. Y

Cn Sheet No. 6 is shown another form of constructing mygenerator, wherein the ilues C C C are horizontal, andthe pipe F is led around and through the series, as circumstances should dictate. Thisform of the generator is constructed with the common return Hue.

I make my generator of such material as will answer the purpose, such as commonboiler iron. Steel could be used to a great advantage, as the expense of manufacturing steel is being greatly reduced by modern improve,- ments in 'that art. i

Having thus described my invention, what I claim as new, and desire to secure b'y Letters Patent, is-

1. In a steam-generator the use and employment of the tube F, for the4 purpose and in the manner substantially as described. V

2. Combining the tube F with the ues C C C, in the manner substantially as described.

3. Combining theI reservoir D, pipe F, and iiues C C C, substantially as described.
